Class AnalyzeDocumentChain

Chain that combines documents by stuffing into context.

Example

const model = new ChatOpenAI({ temperature: 0 });
const combineDocsChain = loadSummarizationChain(model);
const chain = new AnalyzeDocumentChain({
  combineDocumentsChain: combineDocsChain,
});

// Read the text from a file (this is a placeholder for actual file reading)
const text = readTextFromFile("state_of_the_union.txt");

// Invoke the chain to analyze the document
const res = await chain.call({
  input_document: text,
});

console.log({ res });
